Abstract
The present invention relates to degradable plant fiber packing bag and its production process. The production process includes the following steps: 1) soaking wheat stalk in lime water with lime 40 wt% and water 60 wt% inside a pond to react to eliminate outer sebum, and milling the wheat stalk into slurry; 2) weaving cotton yarn in a loom to produce netted tubular cloth; 3) setting the netted tubular cloth between two rollers in a papermaking machine, flowing the slurry into between the two rollers for combination with the cloth, filtering out water and stoving to produce blank; and 4) cutting the blank to form the packing bag. The present invention is favorable to environment protection.
Description
Technical field
The present invention relates to packaging bag, particularly a kind of degradable plant fiber vest shape packaging bag and preparation method thereof.
Background technology
Often use the packaging bag of plastics vest shape in people's daily life, this plastic packaging bag generally is the non-degradable material, and is harmful to environment, is unfavorable for environmental protection.
Summary of the invention
Task of the present invention provides a kind of improved degradable plant fiber packaging bag and preparation method thereof, and it has solved existing plastics vest shape packaging bag non-degradable and environmentally harmful problem.
Technical scheme of the present invention is as follows:
String is adopted in a kind of degradable plant fiber packaging bag and preparation method thereof, and it is wheat straw, Chinese alpine rush, reed, bamboo, cotton that the wheat straw bar is arranged, and is main raw material with more than one strings wherein, by following method preparation:
(1) reclaims and concentrate harvesting residue wheat straw bar behind the wheat, deposit in the melt pit of cement brick wall structure, again the limewash that contains 40% lime and 60% water is injected in the melt pit, the wheat straw bar is immersed in the limewash, near coal-mine tightly with the plastic sheeting lid then, make it airtight;
Wheat straw bar and limewash produce chemical reaction in melt pit, slough the outer sebum of wheat straw bar voluntarily, and this reaction skimming processes needs 7～10 days;
The wheat straw bar that soaked in limewash is taken out from melt pit, wear into slurry, put into that to join stock tank standby by fiberizer;
Chinese alpine rush, reed, bamboo are also used above-mentioned same method degreasing, defibrination, the surperficial blue or green bamboo skin of need shooting off before the bamboo degreasing, well-thought-out plan subbundle;
(2) select cotton yarn, be made into netted reel cloth with loom;
(3) adopt common paper machine, above-mentioned slurry is transported to the hopper of paper machine, slurry is flowed in two cylinders of paper machine front end gradually, simultaneously the cotton yarn screen cloth that weaves is transported in the middle of two cylinders, two cylinders are clipped in cotton gauze cloth among the slurry of input gradually, make cotton yarn screen cloth and slurry combine, and enter drainage and drying system then together, by flattening, drying, produce blank paper;
(4) by the size cutting blank paper of required vest shape packaging bag, adopt automatic doubling labelling machine or be folded in half into the seam machine automatically, make the reel blank earlier, again according to the dimensions of vest bag, carrying mouth and lower bag mouth good seal on the vest bag, become oblong-shaped, the redundance excision of carrying mouth on the vest bag, form the packaging bag of a kind of degradable plant fiber vest shape thus then.
It is main raw material that string is adopted in degradable plant fiber packaging bag of the present invention, but with after abandon natural degradation, help environmental protection.
The specific embodiment
It is strings such as wheat straw, Chinese alpine rush, reed, bamboo, cotton that the wheat straw bar is selected in degradable plant fiber packaging bag of the present invention for use, is main raw material with more than one strings wherein, adopts following preparation method:
(1) reclaim and concentrate harvesting residue wheat straw bar behind the wheat, deposit in the melt pit, melt pit can be built into the ordinary cement brick wall, and the area size is decided as required.Again the limewash that contains 40% lime and 60% water is injected in the melt pit, the wheat straw bar is immersed in the limewash.Near coal-mine tightly with the plastic sheeting lid then, make its periphery airtight.
Wheat straw bar and limewash produce chemical reaction in melt pit, slough the outer sebum of wheat straw bar voluntarily, and this reaction skimming processes generally needs 7～10 days.
The wheat straw bar that soaked in limewash is taken out from melt pit, wear into slurry, put into that to join stock tank standby by fiberizer.
Chinese alpine rush, reed, bamboo are also used above-mentioned same method degreasing, defibrination.The surperficial blue or green bamboo skin of also need shooting off before the bamboo degreasing, the well-thought-out plan subbundle.
(2) select cotton yarn, be made into netted reel cloth with loom.Available 21 cotton yarns are weaved cotton cloth, and also available 10 cotton yarns or 6 cotton yarns are weaved cotton cloth, and the aperture of cotton yarn screen cloth can be the 1cm size, also can be the 0.5cm size.Because 21 cotton yarns are spun yarns, the packaging bag load-bearing material of being made by the spun yarn screen cloth is light, and the packaging bag of being made by the higher cotton gauze cloth of number is can supporting power big.
(3) adopt common paper machine, above-mentioned slurry is transported to the hopper of paper machine, slurry is flowed in two cylinders of paper machine front end gradually, simultaneously the cotton yarn screen cloth that weaves is transported in the middle of two cylinders, two cylinders are clipped in cotton gauze cloth among the slurry of input gradually, make cotton yarn screen cloth and slurry combine, and enter drainage and drying system then together, by flattening, drying, produce blank paper.
Making this blank paper can design according to the bearing capacity of packaging bag, all can take in and implement to accomplish in design to the cotton yarn thickness of the cotton yarn screen cloth that added, the thickness and the whiteness of blank paper.
(4) by the size cutting blank paper of required vest shape packaging bag, adopt automatic doubling labelling machine or be folded in half into the seam machine automatically, make the reel blank earlier.According to the dimensions of vest bag,, become oblong-shaped again carrying mouth and lower bag mouth good seal on the vest bag.The redundance excision of carrying mouth on the vest bag, form the packaging bag of a kind of degradable plant fiber vest shape thus then.As size blank paper is carried out cutting, then can make the packaging bag of other shape by other shaped package bag.
In order to control production cost, cut redundance can be put back to and join stock tank, the reslurry reuse.
Consider the fibre structure difference of various strings, in preparation, the collocation of strings such as wheat straw bar, Chinese alpine rush, reed, bamboo, cotton can be selected for use.In plant fiber material, can contain 70% wheat straw bar, 20% Chinese alpine rush, 10% bamboo fiber and cotton; Also can contain 70% wheat straw bar and reed, 20% Chinese alpine rush, 10% bamboo fiber and cotton.
In joining stock tank, can add 5% waterproofing agent and 5% wet strength agent, and fully mix, treat to strengthen water-proof function behind the finished product by the slurry gross weight.
